派生类的 C++ 构造函数，其中基类包含类成员

Question

给定这段代码

class Address
{
  private:
    char * streetName;
    int houseNumber;
  public:
    Address(char* strName, int houseNumber)
    {....}
 }

class Person
{
   protected:
       char *name, * phoneNumber;
       Address addr;
   public:
       Person(char* n, char* pN, char* stN, char* hsN): addr(stN,hsN)
       {
           //...... assign variable for person
       }      
};

class Officer: public Person
{
    private:
        double salary;
    public:
        // How to write the constructor??
        Officer(char* _name, char*_phoneNumber, char* _streetName, int _streetNumber, double _salary): .... ????
}

如何为派生类 Officer 编写构造函数，它有五个输入变量，其中 _streetName 和 _streetNumber 将被提供给基类​​ Person 中包含的成员对象 addr？

Answer 1

您不能直接在派生的 class 初始化列表中设置基成员。

Officer(char* _name, char*_phoneNumber, char* _streetName, 
        int _streetNumber, double _salary):
     Person(_name, _phoneNumber, _streetName, _streetNumber),
     salary(_salary)
